The larvae quit the wheat in August, and pass the winter in the ground. III. INSECTS INJURIOUS TO CULINAKY VEGETABLES. Spring Beetle or Ship-jack. — Gardeners remark, often to their great annoyance, that many newly-transplanted lettuces begin suddenly to wither and perish ; this happens chiefly ip spring and summer. If we seek for the cause, we find in the roots of the withering plants a worm, which is the larva of one of the Elateridae, which much resembles the meal-worm. It eats, by degrees, the root of the lettuce as far as the collar from which the leaves are developed. It is light yellow, from six to seven lines long, of the thick- ness of a pigeon's quill; its body is cylindrical, somewhat flatly compressed at the head, rather pointed behind, with strong, black, and shining jaws. The pupa or nymph is shorter than the larva, paler in color, and thicker. The beetle, which is developed from the pupa in fourteen days, is from four to five lines long, one and a half lines broad, and has the usual form ot spring beetles; it is slightly curved ; head and thorax dark-brown ; wing-cases yellowish, striped, with dots; the feelers are slender, notched, and yellow- ish-brown ; the under side of the body also brownish. To get rid of this pest, pull up every plant that begins to wither, and kill the enemy within, or in the earth near the plant. Asparagus Beetle. — There are two kinds. One is blackish-green, the thorax red with two black dots, yellow wing-cases, the suture and three spots united to it on both sides black; and the other, called the Twelve- epotted Leaf-beetle, is red, the wing-cases lighter, each havi
